I do need to keep calm :P
I always promised myself to not buy a new computer just to play games. I managed with Bioshock, I have to do the same with Diablo III.
I have to confess that I only played Titan Quest which bored me in Legendary mode as it's not funny to be barely invincible (yes me elementalist IS :p) and to always kill the same mobs, and Diablo III could be very interesting ^^'

No. Stay strong. Don't think about it ! XD
